Growing Sunset Hyssop
Plant it in full sun. It prefers moderate water. It is hardy in USDA zones 6–11. Expect it to reach about 2.5 ft tall and 1.6 ft wide at maturity, in roughly 1 year.
When to plant Sunset Hyssop
Plant Sunset Hyssop in early spring as soon as the soil is workable, or in early fall at least six weeks before your first frost, so roots establish in cool weather. For the middle of its hardy zones 6 to 11 range, spring means February to April and fall means September or October. Once settled, it blooms from June to October.
Month-by-month timing for your zone is on the planting calendar: for the middle of its range, start with zone 8 in February.
